Study-Guide-psychopharmacology Exam Questions With Solutions Gray Matter: The cerebellum, cerebrum, brain stem, and butterfly-shaped portion of the central spinal cord are comprised of gray matter which contains neural cell bodies, axon terminals, dendrites, and all nerve synapses. It is the working area of the brain and the focus of psychiatry and neurology. Gray matter is associated with learning. Changes in the gray matter are linked to psychiatric diagnoses including Alzheimer's dise...
